if you think you have a abcess for god sake dont leave it, i went ot dentist on friday, given pain killers and antibiotics, by saturday my face and neck were massive, went and saw another dentist same day, got told to keep taking tablets, i was in agoney. by the monday i phoned a ambulance to hospital i went, got operated on that night, as i ended up with scepticimia, i also had a drain in my neck, so my advise is tell them you dont want tablets just take the tooth out!!!!
